In order to check the durability of the roof-bearing structures of the Salaspils cultural center “Energetiķis”, the construction company “Pro Dev” carried out 20-hour-long loading experiments on two trusses. The test results are still being collected, but the measurements clearly showed the stability of the structures, informs Mārtiņš Korņejevs, Head of the Construction Department of SIA “Pro Dev”.

“The reconstruction of public buildings built many decades ago according to today’s needs is becoming more and more popular. It is both rational, as it allows to preserve the cultural heritage, and also sustainable, as the already built constructions are reused. The architects have created a wonderful project for the renovation of “Energētiķas”, but the building is very dilapidated, has not been seriously repaired, and its condition has not been improved even by the previously unsuccessful reconstruction. Therefore, we had to make sure in practice whether the project is technically feasible in the intended way, or whether we need to think of other solutions,” explains Kornejevs.
The bearing capacity of the roof of the Culture House was checked by loading two trusses (double-sloped reinforced concrete beams) with sandbags and strain gauges and data loggers ordered from the USA according to a pre-developed program, measuring structural transitions and deformations (deflection). 185 sandbags, each weighing 565 kg, were placed on the roof in a certain form and order. It took about a week to prepare the 20-hour-long experiment, involving both the client of the construction works – the Salaspils County Council, the constructors, and the employees of the main contractor. In order to obtain data for research, several researchers and students of Riga Technical University (RTU) participated in the experiment.
“We like to get involved in such ‘field’ experiments because they happen relatively rarely. They are very interesting for researchers, because in reality we see the behavior of structures in different stages of loading. In the specific case, the results were absolutely expected, these are typical precast reinforced concrete structures – high load-bearing capacity beams, which are found in many places on the territory of the former Soviet Union. The structures of the Salaspils Culture House have no mechanical damage, and they are suitable for taking the loads provided for in the building project,” says Sanita Rubene, assistant professor of the Faculty of Construction and Mechanical Sciences of RTU, researcher of the Institute of Construction Engineering.
The researcher admits that the question of how to optimally check the durability of real building structures is important when moving towards sustainable construction and the reuse of building materials in the reconstruction of buildings. If a sufficiently large amount of data had been accumulated, then modeling could be carried out, but unfortunately, similar experiments are carried out quite rarely in Latvia. During the loading of the roof of the Salaspils Culture House, observations were also made by two engineering students, who will use the obtained data in writing their diploma projects. They also participated in the preparation of the experiment.
During the reconstruction, the Cultural House “Energētiķis” will undergo a large-scale reconstruction and extensive strengthening of the structures to be preserved. Part of the building will be dismantled, while the large hall with 500 seats and the stage will be preserved. It will be supplemented by new rooms – the small hall, ballet hall, classrooms, a spacious lobby.
“When carrying out construction works, we take into account all conditions, including the specifics of the object’s work and its condition, as well as adhere to the work execution schedule. Dismantling is currently nearing completion, these works have been completed to the extent of 96%. Strengthening of structures (earthworks), 75% completed, and construction of foundations – 60% in volume. We are currently working on the construction of internal and external engineering networks – water pipes and sewerage systems – the new underground heating networks have already been completely built and switched. Improvement of the territory has also been started: we are dismantling useless vegetation, a children’s playground, we are making a trench on the surface of the ground. The 18 trees growing on the construction site have been transplanted,” says the head of the Construction Department of SIA “Pro Dev” about what has been done.
